The values given in parentheses are mathematical sstm to SI units that are provided for information astk and are not considered standard. D Corrosion c82 Plies 1, 2, and 3 shall gel before structural plies are added.
Next apply the specified surface mat, rolling so as to draw the resin through the mat for thorough wet-out and deaeration. Flexural modulus— psi MPa. NOTE 5—Maximum flame spread designation c852 Test Method E 84 relates to measurement and description of the properties of materials, products, or systems in response to heat and flame under controlled laboratory conditions and should not be considered or used for the description or appraisal of the fire hazard of materials, products, or systems under actual fire conditions.
In all cases only the current version of the standard as published by ASTM is to be considered the official document. There is no known ISO equivalent to this standard. No plies may be omitted. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.
Gaps are not permitted. For 5 by 4 square weave roving, the approximate relationship is shown in Fig.
E Structural lay-up may be interrupted at intervals long enough to exotherm if required by the laminate manufacturing procedure and 6. Consolidation of the composite laminate is by rolling. As an alternative, a minimum of two passes of chopped roving minimum? Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at xstmfaxor service astm. As an alternative, a minimum of two passes of chopped roving minimum fiber length 1 in.
The resin matrix is applied by various methods, including brush, roller, or spray gun. However, results c5882 this test may be used as elements of a?

NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. Historical Version s – view previous versions of standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
C — Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. NOTE 8—The addition of? When v582 items are required, limits for each shall be agreed upon between the fabricator and the buyer. Your comments are invited f582 for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
See Table 1 and Table 2 for standard thicknesses. D Test Method D Location of astmm plies may be shifted ashm the laminate body. D Foreign matter must not penetrate the surface and must not contribute to entrapped air or other defects not allowed.
These products shall be a commercial grade of E-type glass fiber with a sizing that is compatible with the resin. NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples.
ASTM C582 – 09(2016)
This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement. A thixotropic agent may be added to the resin for viscosity control. They are not arbitrarily selected values. D Corrosion barrier Plies 1, 2, and 3 shall gel before ashm plies are added.
The abbreviation for reinforced thermoset plastic is RTP. Tensile strength, ultimate— psi 62 MPa. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Surface resin may require the addition of paraffin or may be sealed with overlaid film, as required or approved by the resin producer, to ensure proper surface cure. Flexural strength, ultimate—18 psi MPa. See Table 1 and Table 2 for standard thicknesses. It is informational only and not an official part of the standard; the full c852 of the standard itself must be referred to for its use and application.
Asrm 8—The addition of fillers, dyes, pigments, flame retardants, and thixotropic agents may interfere with visual inspection c5882 laminate quality. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

However, results of this test may be used as elements of a fire risk assessment that takes into account all the zstm that are pertinent to an assessment of the fire hazard or a particular end use. C Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. Calculated thickness for design purposes is determined as follows:
